FUEL COMBUSTION METHOD AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2007 - IPC F23C7/00 

FIELD: power, transport and chemical mechanical engineering, possible use in gas-turbine plants.

SUBSTANCE: in accordance to fuel combustion method, fuel stream is separated at least onto three jets, which are fed successively in different cross-sections into air flow, after that fuel and air are mixed in different cross-sections to create a "weak" homogeneous fuel-air mixture, which is then fed into half-limited space filled with hot combustion products, where aforementioned mixture burns with creation of combustion products and emission of heat. Fuel jets are fed into air flow in such a way that a certain relation is maintained between characteristic times. Burner for realizing fuel combustion method contains external cylindrical manacle ring, blade air swirler coaxial with aforementioned manacle ring, circular pre-chamber, at intake of which fuel-dispensing device is provided.

EFFECT: increased stability of burning process.
